there are 6 bolts connecting the trany to the engine. They all should be easy to take out. Are you talking about the three nuts that are used to bolt the trany torque converter to the flexplate? If so, rotate the flexplate to reach the other 2 nuts.

Had the same issue with our 1999 chevy astro van, would crank but would not start. It had been raining and windshield had a leak, after 2 days of no rain it started. Pulled codes and was the Security system in the ignition switch. Hope this helps.

I don't know what's causing the jump but, to reset the light you use an OBDII scan tool. Some parts stores like Autozone and Advance will read the codes for you for free. You could ask them to reset it after he reads them.

Considering the history I suggest the next step should be to take a look inside the fuel tank. It is far from unknown for rags, plastic bags and suchlike to find a way inside and water ingress can also be a problem. Once you can be assured of a consistent fuel supply the task of diagnosis can go forward. It is important to try and locate the problem while the problem actually exists because some electrical and mechanical faults do not leave a trail. A temporary tell-tale light could be fitted to the fuel pump supply for instance, as could a fuel pressure gauge. These things over time will provide clues toward finding the fault. Your mechanic friend could show you how to check the spark for yourself or the injector pulse and lend you the tools... Something that happens so rarely and seemingly randomly is likely to have an underlying pattern; length of journey, weather, place you bought fuel, parked on a hill and so forth. Finding the pattern can be invaluable. Good luck!

Before you replace the injectors have them do an injector balance test. Normally wet weather does not effect fuel system. Sounds more like you have a crank or cam sensor acting up.

Fuel sending unit has likely gone bad, inside tank

How do we know how you have it wired ? You have power and grounds where they belong . Are the B+ wires hot - battery voltage ? What Radio are you replacing ? Base - uplevel ? Did the factory radio have speed compensated volume control . Did it have rear radio control ? It should have 2 B+ power feeds .

If the light is on there are code stored ! Not in the PCM/ECM engine computer . In the BCM , do you know what that is ? body control module ! Need a factory scan tool or equivalent to check !

The right fix could be cheaper then ruining your vehicle . Chopping up wiring harnesses . Their are by pass module , don't know how much they are . It may or may not fix the problem . Pulling the code and doing the diagnostics is still the best solution .
